T0 aZZ whom, it may concern-.-

Be it known that I, WILLIAM M. KELLOGG, a citizen of the United States,residing at Pittsfield, in the county of Berkshire and State ofMassachusetts, have invented certain new and useful Improvements inKnife Sharpeners, of which the following is a specification.

This invention relates to certain improvements in knife-sharpeners, andhas for its ob'- j ect to produce a sharpener which will be simple andefficient in operation, which will be extremely light in weight andcompact in structure, and which can be manufactured and sold at anominal cost.

With these objects in view the invention consists, essentially, of abase having an emery-stick attached thereto and provided with anabrading-block located in a recess therein, said recess being peculiarlyconstructed, so as to enable an unskilled operator to quickly andperfectly sharpen any knife.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings, in which igure 1 is a perspective viewshowing the operation of the device. Fig. 2 is a longitudinal sectionalview showing the location of the abrading-block and the peculiar shapeof the recess. Fig. 3is a detail perspective view of the parts.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The numeral 1 designates the base, which is preferably formed of arectangular piece of wood, which is provided at one of its ends with arecess 2 for the reception of an end of the emery-stick 3. The base 1 isprovided with a peculiarly-shaped recess 4, the base of which is formedwith a slot 5, by means of which the abrading-block 6 is secured inposition. This abrading-block is preferably formed of a flat file, theserrations of which run at an angle to the edges of the block. At theupper portion of the recess 4 the sides thereof are flared outwardly, asseen at 7, and

, form guides against which the sides of the knife-blade are held duringthe sharpening operation. The sides of the recess 4 are bulged ordepressed at a point between the flared portion 7 and the slot 5, so asto form a chamber 8 for the reception of the filings.

As shown in the drawings, the sides of the depressed portions 8 on theopposite sides of the recess 4 lie in the circumference of the samecircle, which feature greatly facilitates the construction of the deviceby enabling both of the longitudinal chambers 8 to be simultaneouslyformed by boring into the base-block from one side thereof. The upperedge of the abrading-block 7 is provided with a cap 9 of any suitablesoft material, which projects slightly beyond the sides and form guardmembers, which prevent the scratching of the knife-blade by a carelessoperator.

In operation the knife-blade is placed against the flared portion 7 andthe sides of the recess 4, and this causes it to take the proper bevelwhen drawn back and forth across the abrading-block 6. An importantfeature of this invention resides in the fact that the filingsimmediately drop down into the chamber 8 and do not accumulate aroundthe knife-blade and interfere with the free operation of the device.

Another feature to which attention is called is ing-block 6, which inconjunction with the wooden sidesiof the recess 4 prevent the sides ofthe knife-blade from being scratched by contact with the abrading-block.After the coarse work has been accomplished by the use of theabrading-block the knife is put in a trim condition by rubbing it backand forth a number of times upon the emery-stick 3.

While I have described the base 1 as being rectangular, it mustbeunderstood that it can be made in any suitable shape or size withoutdeparting in any manner from the spirit of the invention.

Having thus described the invention, what is claimed as new is 1. In adevice of the character described, the combination of a base-blockhaving a recess therein, an abrading-block located in said recess, and aguard member of soft material projecting from the sides of theabrading-block near the outer edge thereof.

2. In a device of the character described, the combination of abase-block having a the cap 9 of soft material upon the abrad- Intestimony whereof I afiix my signatu in presence of two Witnesses.
